'clined position at the -center of the machine, mechanism shown in Fig. 1. Fig. 3 is a view --as upon a bar 2411: secured to the side parts of in vertical lcross section on planev denoted vthe frame, and has a stop 25 to limit the'o movement` of a sheet of paper on to thisl lta'ble.` Aspair of folding rolls 26-2'7 are supported on shafts mounted in the side parts ofthe frame, these rolls being located under the table 23 and preferably about the' 85 len h of the creasing rbllsfherelnabove descri ed. The upper roll 26'has a groove or grooves .-28, the depth of which is shown in dotted -lines in Fig. 2, said groove or grooves being of a width to receive fingers 29 on a folder blade 30 secured t the end of a folder `arm 31 carried by a folder 4shaft 32 mounted in bearings 33 on the side parts of the frame; 'Y

A folder 'actuating arm 34 is secured tothe shaftl near one end and carries 'a7 folder' actuating bar 35 forked at its end to straddle the shaft of the lower creasing roll A12, as shownin dotted lines in Fig. 2, this bar bearing a roll 36 resting against Aa folder actmting cam 37 which is of proper shape to per- 10Q form the wo'rk required of 1t. l

In the' operation of the ,machine thus far a blank. passing to the rolls 11-12 is creased 1 substantially midway ofits lengthby the action of the'rib'13'and'jrecess'14. At the' los time theblank is beingf delivered from these rolls tilting table 161is in the position :Shown in dotted lines in Fig.s2, so "that the-sheet of paper is directed upward ,lento the folding table'.23fandfngainstshe ,119

preferably widest ata the bottom, fitting` 'to a knuckle part 72 pivotally mounted :is

,the proper time to enable the folder blade f .5.3730 to engage the blank at or in the vicinity disks having mucilage strips 40 arranged thereon to make 'contact with the .each other b means of cams 66 mountedon 'tions of the slideways, andhaving secured stop 25. The table 16 is tilted-downward at of the,creased portion above described and force it linto the opening between the ed fe ofthe folding table Q3 and the tilting tab e 16, thus doubling the blank ci'osswise and` tucking it between the folding rollsZtL-Z', the fingers 29 in this operation passing into the `grooves 28. The tilting table rain 2l and the folder actuating cam 3',"v are of such form and will travel at such speeds asto cause the timely operation of the tilting table 16 and the folderv blade 30 to perform the operation described and permit travel of the blank 'in the manner set forth.

A shaft 38 bearing mucilage disks 39 is mounted in the sideparts of the frame, these rojecting edges of the crosswise vfolded b ank 'as it passes between the mucilage disks and a feetl roll 41. Theblank is`of such shape that when` folded crosswise by the folder blade 30 the lower fold is `wider than' the upper fold,l projecting beyond each. edge ofv the latter.,` these projecting ed es .being, daubed with niucilage, so that in t e folding. mechanism to be hereinafter described.'these mucilaged'edges are folded: over upon-,the top fold. A table 42 extendsfrom a' cross bar 43 supported by `the side parts of the. frame, over which the blankstravel to folding mecbimism to 'be described, :g \yk A folder support 63 is ri 'dly'seci'ired` 'to' and extends between the sigb parts 10, 'the table 42 resting upon this support. Folder.

slides 64 are/mountedA in slidewa s 65 inithe Y' support and are moved tower and yfrom the cam sha t 67 supported in the side arts and driven by intermeshing gears to be 1ereinafter described, the cams operating as against rolls secured to the underside of the slides, as shown in 'Fig 3. The slides are within the wvidcrfport-ions 68 of the slideways, thc'narrower upper part of the slides proJectingr through the narrower upper porthereto 'felder bases 65) of a length to profject beyond the edges of the slideways andthus form a support `for the slides which'are sustained thereby. -Plates forming a fol-ling box are secured to the upper side of the folder support (53, these plates having branches 44 forming part Vof the slideways for thefoldr slides, the edge bars 45 constituting the -box within which the blank is folded. The bases 69 have ears 70 between which folder blades 71 are pivotnlly mounted, as herein vshown each blade being secured quired o ports as by described, although the blades Amay if def, sired be formed in a single piece. The table 42 is of such width that grooves .46 are waifdly projecting edge forming a stop 51,

constituting, in faCt,-the -inner edge of the folding box. This stop plate is operated by 'a stop plate cam 52 secured to the side of the lower folding box feed roll 54, a shoe 55 being shown herein to receive the direct thrust of the cam.

A forming plate bar 56 is rotatably mounted in the' side parts of the frame, this bar having an yarm 57 and a s ring 58, preferablylocatedat one end of tiie bar, to hold, the bar with. the former plates to be described normally in-'a raised position. A4

forming bar operating arm 59 is also secured to theforming bar, preferably at the end opposite said arm 57, and a cam rod 60 i straddles the shaft 61 of theupper folding pivotally attached to the arm extends to and box feed roll 62, the rod dirrying a roll in late o rratn the preferredform of connection shown herein the carni-.od 60 has a. slot 87 within which the pivot extending from the arm 59 is 1ocated, and a spring 88 with one end secured yengagement 'with a forming io the pivot and thelothcr end to the rod 60 provides a yielding connection, enabling theA forming plates 81- to have a ermissive yield-I ing movement to accommo 'ate them to vit-' i-ioiis -conditions asto the thickness of material within .'the vfolding box, whichnia occui'- from' accidental waddingof the b a'nks or for other causes. This cam- 73 is so shaped and timed that it will impart the ,necessaryv movements to the forming plates to bellicreinaftcrfdescribed, so` that the latle: will 'properly perform ythe functions re-` tliem andat the proper times.

The forming plate bar 56 is-preferably of angular shape inV cross section at'its center, as shownn-n .Fig.-2 of the drawings, and upon this: angularly shaped part forming plate supports 74, (two in number-)J are'sli'dably mounted, this movemcntbeinglim'ited by any .suitable means. Pivot plates 76 lare adjustahljvi secured to the forming plate=s`up in cans of screws- 75 passing through slots 1n the plates,' and fforming plate slide. levers 77 are connectedthoreto,

saidlevers bein pivotally mounted-Jon suppoitiiigpla-tcsy 8 extending 'from the side parts of the frame. 'Forming plate slidei rods. 79 are ivotally connected with each of theylevers 7 said rods also straddling the shaft 61 and *having rollers in engagement with formin plate slide cams 80. These cams are so s aped and timed in their movements as to impart sliding movement to the forming plates at such times and to such exytents as that the latter shall properly perform the functions required of them. Formingplates 81 are supported by t-he forming plate supports 74, as shown in Fig. 2 of the drawings, ribs 53 receiving and supporting the mucilaged folded edge of the blank from contact with the surface of/the plate and preventing the smearing offsaid plate with lmucilage, these plates overlying the folding box and being of such shape that when `in certain relative positions they will .just fill the box widthwise,'theedges of the box and the forming plates tapering slightly from the' front end of the box to the rear end thereof.

Presseicams 82 overlie the folder blades 7l in position to make contact therewith to press the bladles downward against the folded over edge ofthe blank, causing it to be pressed firmly into engagement with the upper fold ofthe blank and insuring perfect adhesion of the parts. The upper folding Vbox feed roll 62 is'cut away for a portion'of the distance around its periphery leaving a feeding arc 89 which is of suflicient extent to properly move a blank from the folding box to a point where it will be acted upon by the feedIk rolls 83-84, and at the same time feed a blank from the rolls 39-41 into the box against the'stop 51. After leaving the box the blank is conducted for such other 'operations as may be necessary as by feed rolls 83-84.

' In the operation of this part of the folding mechanism the blank is fed into the ,folding box by the rolls 54 and 62, in the arrangement herein shown, the incoming ,blank being gripped 'by the feeding are 89 at some point back of the center of the are, substantially the last quarter of .this arcbeing sutlithe projecting edges of the lower fold of thel "blank extending beyond thrselifting strips and on to the edge bars cient to move the blank against the stop 51, which is at this time in its raised position. The advance portion ofthe feeding `arc 89 removes the blank which has been folded and at the same time the rear part is bringing a new blank into the box, there being a slight distance between the outgoing and incoming blanks. The blank as it enters the box rests upon the lifting strips 47, 'which are raised,

45 of the box. The forming plate operating cam now rocks the bar to, bring the plates down on.to the blank, the plates The lifting strips are thus pressed down and the'projectin edges of the under fold of the blank are raised, as

at this time being separated tol Hnicely fit the box.

shown in Fig. 4: of the drawings. The cams 66 now operate to permit the folder blades 71 to move toward each other, under the influence of the folder blade springs 90, the blades contacting with lthe projecting edges of the blank and folding th'em over on to the former plates 81. The presser cams 82 now come' into contactwith the folderblades 71, the forming plates 81'having been moved to-L ward each other and from underneath the folded edges of vthe blank by the cams 80 just before the cams 82 res's upon the folder blades 71. The proJecting'edges of the lower fold of the blank are thus pressed firmly into engagement with the upper sur face of the upper fold of the blank, when the cam 66 engages the folder slides andcauses them to move back., As the folder blades 71 rise the lifting strips 4.7 lift the blank to a' level with the up er surface of the edge bars ll5 so that the lank may, now be inoved thereover and out from the folding mechanism by the action of the rolls 54 and 62. lVhile the forming lates 81'are in their raised positions the orming plate cams 80 operate to permit the forming plate springs 91 to draw the forming plates apart preparatory for downward movement, to press a blank into the folding box. After the presser cams 82 have operated upon the folder 95 blades, the latter are separated by the action of the cams 66, and after a blank has been started out of the folding box the stop plate mm comes in contact with the shoe raising the stop' plate from the position shown in Fig. and placing the stop 51 in position to limit the movement of the incomingblank into the box. Under the action ofl the cam 52 the stop plate is permitted to lower to the position shown in Fig. 2 where it is held by a stop plate rest 92.

',The several rolls are driven by gears upon the .severaly shafts meshing one with another in any manner that may bev desired, and this forming no part of my present invention a detailed description is omitted herein, it be ing briefly stated that the driving shaft 85 is supported in the side parts and has a driv ing pulley 86, said driving `shaft having gears'meshing with interengaging gears on other shafts of the machine to properly `drive the several parts to perform their several functions.
